Not sure what you're supposed to be doing here, but if you're supposed to factor...
-12*-10 = 120
-12+(-10) = -22
Thus,
(c - 12)(c - 10) = 0
c - 12 = 0
c = 12
or
c - 10 = 0
c = 10
Answer:
C. C is the only one that is rational out of all of them. The rest are irrational
20/29 is the cosine of theta
<span>For the answer to the question above, according to Weber's law, the perceptible differences are proportional to the initial perception. So, with just a 10% increase in area was perceptible, but an increase of 1-9% in the area is considered imperceptible. The 9% increase in area reflected by 200 to 218 would be perceived as the same size as before.
The <u><em>answer is 218</em></u></span>
